Quercetin Working at its Fullest Potential
While quercetin is well-known for its potential to support a healthy immune response, respiratory function, and healthy histamine levels†, the fat-soluble flavonoid can also be difficult for the body to absorb.*GammaSorb™ graphic

Frequently Asked Questions

How does GammaSorb™ work?

GammaSorb (gamma cyclodextrin) improves the absorption of fat-soluble nutrients by enveloping them in a water-soluble shell. To be more specific, the gamma cyclodextrin plant-derived molecule surrounds fat-soluble ingredients in an open-ended microscopic structure, the exterior of which is water soluble. This escorts the ingredients to the walls of the intestines for better absorption.

What is the source of quercetin in this formula?

Quercetin is widely available from many foods, including onions, apples, tea, berries, and grapes. However, there are many other botanical sources, such as the flower buds from the Japanese Pagoda Tree (Sophora japonica), which provide the quercetin used in this formula.
